A tiny cluster of Solana bots unlocked a 3x trading advantage by routing through one proprietary protocol
New research into automated trading on Solana found a nearly threefold difference in positive wrapped SOL outcomes inside one small group of bots. Transactions that invoked HumidiFi, which the paper classifies as a proprietary automated market maker, recorded a positive WSOL balance change about 62.3% of the time. Other transactions in the same 12-address group did so at a 21.01% rate.
The comparison covered 244,733 HumidiFi-invoking transactions, including 152,502 with a positive WSOL balance change, and 218,678 other transactions, including 45,949 with a positive change. The rate ratio was about 2.97.
The edge appeared in one narrow cluster
The ASE 2026-accepted paper examined 200 addresses associated with two trading-oriented bot services on the Solana network. The researchers selected the top 100 addresses linked to Trojan and the top 100 linked to SolanaMevBot, then collected their transactions from Oct. 1 to Nov. 1, 2025. They grouped 158 addresses into four clusters using measures such as transaction intensity, execution success, fees, and asset breadth, while treating 42 addresses as noise.
